SSPC Updates 2 Standards
PITTSBURGH—SSPC committees have announced updates to two standards: one for surface preparation and one for polyurea topcoats.
SSPC-SP 1, "Solvent Cleaning," is used to specify removal of visible deposits of oil, grease and other soluble contaminants from metal surfaces before employing additional mechanical means of surface preparation.
All of SSPC's surface-preparation standards require solvent cleaning to SP 1 before performing additional cleaning required by the project specification.
SSPC Paint 39
SSPC Paint 39, "Two-Component, Weatherable Aliphatic Polyurea Topcoat, Fast or Moderate Drying, Performance-Based," can be used to establish minimum performance requirements for a thin-film aliphatic polyurea topcoat that can be used over compatible corrosion-prevention primers or intermediate coats to protect from ultraviolet light.
Because Paint 39 is a topcoat standard, performance requirements focus on color and gloss retention and physical film properties.
